Show If with two chain conditions

Hello community! I need your orientation, I have a column (B) that will be hidden if column (A) is blank, and later the same column (B) should be hidden when column (C) has data, there is some Show If expression for this ?

What do I want to achieve?
Column (A) is employee ID and all columns will be hidden until the ID is validated if it is valid it must show all columns and column (B) is an enum button that only fulfills the function of updating the column Change timestamp (C) and when this column has data column (B) should be hidden again
